[OpenSIPS-Users] lookup() not working as documented

[Bogdan-Andrei Iancu]

Hello Stian,

AOR  nnnn0790 at y.y.y.y  and nnnn0790 at domain.no 
<mailto:nnnn0790 at domain.no> are completly different - according to SIP, 
they do not match or so. So you have to use the same AOR when 
registering the user (AOR will be in To hdr) and when calling the user 
(AOR will be in RURI).

Maybe the doc can be misleading a bit when using the terminology of 
"username" - but this has to be interpreted in the context of 
"use_domain" parameter from usrloc:
     http://www.opensips.org/html/docs/modules/1.9.x/usrloc.html#id292895

So, docs are not clear, we will take care of that!
